Metal Roofing Built for Curtis's Heavy Rain, Snow Loads, Windstorms & Lifetime Protection

Performance you can measure (all climates):
• Precision weatherproof seams (profiles: slate, cedar, shake, tile) and mechanical fastening (profile: standing seam) deliver long-term leak protection during wind-driven rain events
• Interlocking panel system tested to 193+ km/h (120+ mph) for severe windstorms that can impact Curtis and surrounding areas in Lewis County
• Built to shed prolonged, heavy rainfall from Pacific atmospheric river events that periodically affect Curtis, reducing roof infiltration risk
• Aluminum panels are coated with the Alunar® Coating System (no visible aluminum surface) for durable, low-corrosion performance
• Local onshore storms can carry marine salt inland at times; the coated aluminum resists corrosion from episodic salt exposure in Lewis County
• Snow-shedding metal panels reduce buildup and help prevent ice dams during occasional freeze–thaw cycles and light to moderate snow loads near Curtis
• Shade, damp winters, and moss growth are common in this part of western Washington; the smooth coated finish limits moss adhesion and simplifies cleaning on Curtis roofs
• Class A fire-rated available for homeowners who require enhanced fire performance and ember resistance where wildfire risk rises in dry spells
• UL 2218 Class 4 impact resistance helps protect Curtis homes from hail, falling branches, and storm debris
• Advanced waterproof installation methods provide reliable leak protection through Curtis’s wet seasons and wind-driven rain
• Energy-efficient cool-roof behavior reduces summer heat gain, improving attic comfort and cooling loads for Curtis residences
• Engineered for solar compatibility with modern bracket-mounted photovoltaic systems on Lewis County homes
• Fully recyclable aluminum supports sustainability goals for environmentally conscious Curtis homeowners
• Premium architectural profiles replicate slate, cedar shake, and tile for region-appropriate curb appeal while retaining metal durability
• Low-maintenance system designed to outlast asphalt shingles in Curtis’s high-moisture environment and backed by a Lifetime-Limited transferable warranty

Interlock® Aluminum Roofing — all-climates performance specs for Curtis, Washington
| Spec / Rating | Climate / Risk Factor + What It Solves |
|---|---|
| Wind resistance: 120+ mph (193+ kph) | Extreme wind, hurricanes, storm uplift: full interlocking attachment helps prevent blow-offs, edge lifting, and panel loss in high-gust events. |
| Fire rating: Class A (with proper assembly) | Wildfire, embers, radiant heat, chimney sparks: non-combustible roof assembly provides the highest residential fire protection rating. |
| Hail resistance: UL 2218 Class 4 | Hail and impact debris: highest impact classification; resists cracking, splitting, and surface loss common with asphalt under hail strikes. |
| Snow & ice performance: interlocking, shedding profile | Heavy snow, freeze-thaw, ice dams: smooth aluminum sheds snow efficiently and the interlocking design helps block water intrusion when melt-refreeze cycles occur. (Final snow-load capacity depends on roof structure and local code.) |
| Corrosion resistance: aluminum (won’t rust) | Salt air, coastal humidity, wet climates: aluminum naturally resists rust and corrosion, reducing long-term failure risk in marine or high-moisture environments. |
| Heat / UV durability: baked-on coating system | High heat, intense sun, thermal cycling: coatings resist UV breakdown and temperature-swing fatigue, slowing fading and surface degradation. |
| Moss / algae resistance: smooth coated surface | Wet shade, organic growth: low-porosity metal surface gives moss/algae less to grip, reducing staining and maintenance. |
| Material: heavy-gauge aluminum roof profiles (Slate / Shake / Shingle / Tile / Standing Seam) | All-season structural stability: lightweight, dent-resistant metal system stays stable through large hot-cold swings and severe weather. (Add exact alloy + thickness for maximum spec proof.) |
| Expected lifespan: 50+ years | Long-term durability across climates: avoids re-roof cycles typical of shorter-life materials, even in high-stress environments. |
| Warranty: Lifetime-Limited, non-prorated + 50-year transferable | Lifetime protection + resale value: guarantees long-term material confidence and transfers to future owners. |
